Two series of compaction tests were performed in the laboratory

Home » Soil Mechanics » Soil mechanics miscellaneous » Question

Two series of compaction tests were performed in the laboratory on an inorganic clayey soil employing two different levels of compaction energy per unit volume of soil. With regard to the above tests, the following two statements are made.
I. The optimum moisture content is expected to be more for the tests with higher energy.
II. The maximum dry density is expected to be more for the tests with higher energy.
The CORRECT option evaluating the above statement is

1. Only I is TRUE
2. Only II is TRUE
3. Both I and II are TRUE
4. Neither I nor II is TRUE

Correct Option: B

For tests with higher energy (like modified proctor test), optimum moisture content will be lesser and maximum dry density will be higher, than tests with lower energy.
